What is the primary protective equipment used by practitioners when using an electric file?

The primary protective equipment used by practitioners when using an electric file is a dust mask. This type of mask is specifically designed to filter out the fine particles and dust that are generated during the filing process. When working with electric files, small dust and debris can become airborne, which can pose respiratory risks if inhaled. The dust mask helps to prevent those particles from entering the respiratory system, thereby ensuring the health and safety of the practitioner.

While safety goggles, gloves, and face shields offer important protection in various scenarios, they address different risks associated with nail technology. Safety goggles protect the eyes from splashes or flying debris, gloves guard the hands against chemicals and potential cuts, and face shields provide a broader area of protection for the face. However, in the specific context of using an electric file and the unique hazards it presents, a dust mask is the most critical piece of protective equipment.
